Abstract (en)

An optical recording medium (I) comprises an organic dye layer (1), a reflecting layer (2) and a protective layer (3) sequentially on a light-transmittable substrate. (1) contains an organic solvent in an amount of 2 - 15 wt.% based on an organic dye. An independent claim is included for producing (I) comprising : (a) forming (1) by spin coating a solution containing the organic dye and the organic solvent on the substrate; (b) forming (2) on (1) without drying the solvent left in (1); and then (c) forming (3) on (2).

The invention provides an optical recording medium having excellent weatherability and a process for producing the same. The optical recording medium is provided with an organic dye layer, a reflecting layer and a protective layer in this order on a light-transmittable substrate, the optical recording medium containing an organic solvent in the organic dye layer in an amount of 2 to 15% by weight based on an organic dye. A solution prepared by dissolving an organic dye in an organic solvent is applied onto a transmittable substrate by a spin coating method to form an organic dye layer, thereafter a reflecting layer is formed on the organic dye layer without performing a drying treatment of the organic solvent left in the organic dye layer and further a protective layer is formed on the reflecting layer to produce an optical recording medium containing an organic solvent in an organic dye layer in an amount of 2 to 15% by weight based on an organic dye.
